T aZZ whom it may concern:

Be it known that LEVERETT E. RHODE a citizen of the United States, residing at Hartford, in the county of Hartford and State ofGonn'ecticut, has :inventeda new and useful Iniprovementin Vertical-Sihaper Attach-nients, of which the following is a specification. J

. This invention relates-t0 those metal cutting tools known as 'shapers. These inachines are built 'With horizontally reciprocating rains for makinghorizontal cutsand LWl't'l] vertically reciprocating rams for making vertical cuts. The object 'otthis invention is to provide a simple and rigid attachment With a vertically :reoiprocating ram that may be easily and quickly substituted for the horizontally reciprocating ram :and connectdwiththe 19 standard operating infech'anism'for the .pur-

pose of transforming :the horizontal shap'er into a vertical shaper when it is desired to make ve'rticalcut's instead-of horizontal cuts. This object is attained by providing a housing with a saddle carrying a vertical tool holding ram and horizontal lever for re- :ciprocating the ram, "designed in such form that the housing may be seti'nto and secured in the desiredpo siti'on in the tvays at the top of the machine frame in such m'annerthat the cutting pull of the horizontal lever on the ra n is downward and tendssto draw the housing down .upon the fra1ne,.thus insuring rigidity and accuracy of Work for a" long period of time. p

In the accompanying drawings Fig. 1 shows-a verticalsection 'ofa vertical shaper attachment that embodies the invention. Fig; 2-shows a front vieivof the upper portion of the machine frame ivith the housing and horizontal l'e'ver inoperatiye position. 7

The top of the frame 1 of the 'coin 'non form er horizontal sha-per has Ways 2 fcovered by gib plates '3 in which the horizontal rain slides backa'nd forth. fIn carrying out this invention the housing 4 has fastened to its under side bars 5 thatare shaped and lo- -dated to fit in the Ways andjbe securedior holding the housing in position by the' gib plates. The-ram saddle 6 is held iii the front end of the housingby a-pivotlpin Tthat extends transverse ly through i the lower end of the saddle and the forwardly extending sides 8 of the housing. Clamp crewsfl 'P TQlQQt outwardly from the upper end of the saddle through slots 10 in the sides ofthe-housing for securing the upper endofthe saddle. ,By

h s means the sac dile y rpos tionedso thatthe tool ill'fm ake an exact vertical out or the saddle maybeti'lted so that the tool will make an; oblique out on anyjdesireda ngle approximately vertical. With thejsaddle pivoted at'its lowerend the desired angular path of the-tool may be obtained 'WlthQUtcarrying the point or the tool a "great distance forward over the Work table.

The ram 11 is fitted to move up and (lOWIl in'a Way in the front of thesaddle Atjthe lower end of the rain isa box 12. Thisbox is clamped, 'to the botto'm of the ra'm bya binder stud 13 that isdrawn uptvard by the Wedges 14; and screw :16. Held i'n-the :box

point end of the tool forivard. By loosening rotatorily of the ram.

the screw 15 the box andblock may be turned for setting the tool in the desired-position In the rain is a connector :block; 21. The rain is adapted toibe adjusted up or down with relation to this block for raising 'or lowering the tool. by nieans of the feed screw 22 that is turned by the handle 23; When the relation of the rain andconnector 'block are determined, the part'sare fastened together by clarnp screw 24; An ear on the connector block is held between the forked end of the horizontal lever 25 by a pivot pin 26. The other end ofthi's lever isfforked and is free to slide on spool 27 which is mounted on the pivot pin 28 that is supported by the side 'vvallsof the housing. A

. plate 29 is f'asten'edto this forked end of'the lever and, a 'cover pl'ate '30 'is arrang d ever a hand'hole in the li'ousing adjacent to this end of the lever;

" An arm 31 is adju'stably fastened to the movable in a slot 41in the lever.

lever between its ends by a nut32, the arm extending through a vertical slot 33 and the rod 35 with leg plates 36that are fastened to or may be cast integral with the lower end of the crank lever 37 adjacent to the pivot 38 which supports the crank lever. The crank lever is oscillated by the crank'block 39 that is pivotally attached to a gear 40 and is The crank gear is engaged and rotated by a driving pinion 42 in the usual manner.

When the machine is arranged as a horizontal shaper the upper end of the crank lever is connected directly with the ram that is -mounted in the ways at the top of the frame as is well known to those familiar with this type of machine. To set up the machine as a vertical shaper, the housing is placed on the ways normally occupied by the horizontal ram and secured in position by the gib plates, and the connecting rod is back to the horizontal shaper the connecting rod is disconnected from the leg plates and the gib plates unfastened, then the vertical attachment can be removed and the horizontal ram substituted.

position to bring the tool to the required location with relation to the work, before the housing is secured. With the mechanism described the pull of the connecting rod and horizontal lever during the down or cutting stroke of the ram'is straight downward so that the tendency of the forces is to pull the housing down upon the frame. There is no upward pressure on the housing when work is being vdone. This ensures rigidity which is essential to accuracy and relieves the housing fastenings of strain so that the desirable condition will exist fora long time.

The invention claimed is: 1. The combination with a shaper frame having a crank actuated lever, of a housing j secured to the top of the frame, a saddle mounted on the housing, a ram movable up and down on the saddle, a tool holder at tached to the ram, a horizontal lever pivotally mounted in the housing, means joining the lever with the ram, a. connecting rod jointed to the lever, and means projecting from the crank actuated lever, ointed to the connecting rod, whereby the oscillations of the crank lever through the connecting rod and horizontal lever reciprocate the ram substantially vertical.

2. A shaper attachment "comprising a housing adapted to be secured to the. top of a shaper frame which has a crank lever, a saddle mounted on the housing, a ram movable up and down on the saddle, a tool holder attached to the ram, a horizontal lever pivotally mounted in the housing, means joining the, lever with the ram, a connecting rod jointed to the lever, and means jointed to the connecting rod and adapted to be secured to the shaper crank lever.

3. A shaper attachment comprising a housing adapted to be secured to the top of a shaper frame which has a crank lever with an angular extension at its lower end, a saddle pivotally mounted on the housing, means for adjusting the saddlewith relationto the housing, a ram movable up and down on the saddle, a tool holder attached to the ram, a horizontal lever pivotally mounted in the housing, means joining the lever with the ram, and a connecting rod jointed to the horizontal lever and to the angular extension of the shaper crank lever.
